  In the conventional electric reel, the spool sensor or the spool counter may break down due to deterioration or failure of the sensor due to long-term use. In particular, if one of the two reed switches of the spool sensor breaks down, the rotation direction and the number of rotations of the spool cannot be detected, so that the fishing line feeding direction and the position of the device may not be detected accurately. . Thus, if the fishing line feeding direction and the position of the device cannot be accurately detected, for example, if the reed switch fails while the motor is being driven, the driving of the motor may not be stopped.

  For example, if the reed switch breaks down during electric hoisting, it becomes impossible to perform control to stop the mechanism at the shipboard position, so that the mechanism continues to wind up beyond the shipboard and the fishing rod or the like may be damaged. In addition, if the reed switch breaks down while driving the motor and feeding the fishing line at a high speed, it will not be possible to perform control to automatically stop the device at the shelf position. There is a risk that the fishing line will get tangled.

  An object of the present invention is to prevent a problem related to motor control that occurs when a spool sensor fails in a motor control device for an electric reel.

Speed display portion 5e.

  The water depth display part 5a, the bottom memo display part 5c, and the shelf memo display part 5d can display the water depth in three digits. The mode display unit 5b displays the display mode on the screen with one of two types of characters “from the top” and “from the bottom”. Here, the mode from the top is a mode that displays the depth of the device from the water surface based on the electric reel, and the mode from the bottom is a mode that displays the distance from the bottom to the device based on the water bottom. . For this reason, the mode from the top is suitable for fishing a fish called “top thing”, and the mode from the bottom is suitable for fishing a fish called “bottom thing”.

  The operation unit 6 includes an acceleration / deceleration switch SK and a power button PB that are arranged vertically on the right side of the display unit 5, a saddle button IB, a shelf memo button TB, and a bottom memo button SB that are arranged vertically on the left side. Is provided. The acceleration / deceleration switch SK is a seesaw type switch composed of two switches. When the upper switch is pressed, the speed gradually shifts to the high speed side for the time the gear is being pressed, and when the lower switch is pressed, the speed shifts the low speed side. When the pressing is stopped, the acceleration / deceleration switch SK returns to the neutral position, and the gear position at that time is maintained. The power button PB is a button for turning the motor 12 on and off.

  The scorpion button IB is a button that is used when setting a scorpion mode in which a mechanism is struck in the vicinity of a shelf, performing sword learning, or canceling the scorpion mode. The shelf memo button TB is a button for setting the upper shelf position in the mode from the top and the bottom shelf position in the mode from the bottom. If the shelf memo button TB is kept pressed for 3 seconds or more, the water depth display is set to 0. The bottom memo button SB is a button for setting the water depth of the bottom of the water. If the bottom memo button SB is continuously pressed for 3 seconds or more, the display mode is switched from the top mode to the bottom mode.

  An alarm 7 (see FIG. 3) for outputting various alarm sounds is provided on the lower surface side of the operation panel 4.

  This electric reel has a control unit 20 as shown in FIG. The control unit 20 includes a microcomputer including a CPU, a RAM, a ROM, an I / O interface and the like arranged in the operation panel 4 and executes various control operations described later according to a control program. The control unit 20 includes various buttons (switches) of the operation unit 6, a spool sensor 21 including a pair of reed switches that generate pulses to detect the rotation direction and the number of rotations of the spool 10, and the spool sensor 21. A spool counter 22 that counts pulses emitted from the motor 12 and a current detection sensor 23 for detecting a current value supplied to the motor 12 are connected.

  As shown in FIG. 1, the spool sensor 21 includes a first sensor 21 a and a second sensor 21 b that include two reed switches arranged side by side. The first sensor 21 a and the second sensor 21 b detect one or a plurality of magnets (not shown) that rotate in conjunction with the spool 10. By counting this detection pulse with the spool counter 22, the number of rotations (rotation position) of the reel can be detected. Further, it is possible to detect the rotation direction of the spool 10 based on which of the first sensor 21a and the second sensor 21b has issued the detection pulse first. Specifically, when the pulses emitted from the first sensor 21a and the second sensor 21b are the pulse P1 and the pulse P2, respectively, as shown in FIG. 5A, the first sensor 21a emits the pulse P1 first. Detects that the spool 10 is rotating forward (rotating in the yarn feeding direction). Further, as shown in FIG. 5B, when the second sensor 21b first emits the pulse P2, it is detected that the spool 10 is reversely rotated.

  The spool counter 22 is a counter that counts the number of times the spool sensor 21 is turned on and off, and rotational position data relating to the spool rotational speed is obtained from the counted value. The spool counter 22 decreases when the spool 10 rotates in the forward direction and increases when the spool 10 rotates in the reverse direction.

  The current detection sensor 23 detects the current supplied to the motor 12 by detecting the partial pressure at both ends of the FET 25 a that is a motor drive element used in the PWM drive circuit 25. In addition, when using FET with a current detection function, the current detection sensor 23 is unnecessary. Here, the current detection sensor 23 is disposed in the operation panel 4 together with the control unit 20.

  Further, the control unit 20 includes a plurality of timers 8, an alarm 7, a display unit 5, a PWM drive circuit 25 using an FET 25a, a storage unit 26 including a non-volatile memory for storing various control data, and reading. The unit 28 and other input / output units are connected. Further, the motor 12 is connected to the PWM drive circuit 25.

  As shown in FIG. 4, the storage unit 26 stores a display data storage area 30 for storing display data such as shelf positions, and learning data storage for storing learning data indicating the relationship between the actual yarn length and the spool rotational speed. An area 31, a duty table storage area 32 for storing the maximum duty ratio DSU corresponding to the gear stage used in the PWM drive circuit 25, and a data storage area 33 for storing various data are provided.

  In the duty table storage area 32, for example, 50% for the first and second speeds on the low speed side, 70% for the third and fourth speeds, 90% for the fifth speed, and 6% which is the highest speed in the supply voltage of the external power supply 40. The maximum duty ratio DSU of 100% is stored for the 7th speed in the speed and boosted state. Thus, the maximum duty ratio DSU is set to increase as the gear position increases. Further, the winding speed set for each gear stage SC is also stored in this duty table storage area 32.

  The reading unit 28 (see FIG. 3) corresponds to the duty ratio D of the actually set PWM drive, the maximum duty ratio DSU read from the duty table storage area 32, the set gear stage SC, and the gear stage SC. Thus, the target winding speed and the like set are stored.

  The electric reel also includes a switching unit 41 and a booster circuit 42 controlled by the control unit 20 (see FIG. 3). The switching unit 41 switches a route for supplying power supplied from the external power source 40 such as a battery to the PWM drive circuit 25. Specifically, the switching unit 41 sends the supply voltage of the external power supply 40 as it is to the PWM drive circuit 25 according to a command from the control unit 20 or boosts the supply voltage via the boost circuit 42 to increase the supply voltage. Switch between sending to.

  Next, main control processing performed by the control unit 20 will be described with reference to control flowcharts shown in FIGS.

  When the external power supply 40 is connected to the electric reel, initial setting is performed in step S1 shown in FIG. Here, the water depth display is set to “0”, various flags are reset, and the display mode is set from the top to the mode.

  In step S2, display processing is performed. In the display process, various displays such as a water depth display are performed. Here, in the mode from the top, the water depth from the top is displayed on the water depth display portion 5a, and in the mode from the bottom, the distance from the bottom is displayed. When the shelf position is set, the upper shelf position is displayed on the shelf memo display portion 5d when in the mode from the top, and the bottom shelf position is displayed when in the mode from the bottom.

  In step S3, it is determined whether or not a key input has been made by operating various buttons of the operation unit 6. When a key input is made in step S3, the process proceeds to step S7, and the key input process shown in FIGS. 7 and 8 is performed.

  In step S4, it is determined whether or not the spool 10 has rotated. This determination is made based on the output of the spool sensor 21. If it is determined that the spool 10 is rotating, the process proceeds from step S4 to step S8, and each mode process (shelf alarm process, ship edge alarm process, etc.) is executed.

  In step S5, it is determined whether or not the motor 12 is turned on. If it is determined that the switch is on, the process proceeds from step S5 to step S9.

  In the acceleration / deceleration process in step S9, the duty ratio is increased or decreased to increase or decrease the speed of the motor 12. In this processing, the current rotational speed of the spool 10 detected by the spool sensor 21 is compared with the rotational speed data set in the current gear stage SC, and the duty ratio D is adjusted so as to match the two. The rotation of the motor 12 that rotates the spool 10 is increased or decreased. However, the duty ratio D is adjusted within a range not exceeding the maximum duty ratio DSU corresponding to the gear stage SC at that time.

  When the process proceeds from step S9 to step S10, the electronic breaker process of the motor 12 shown in FIG. 9 is performed. The electronic breaker process is a process of detecting the state of the spool sensor 21 and turning off the motor 12 in accordance with the state of the spool sensor 21, and is started when the motor 12 is turned on.

  First, in step S51 shown in FIG. 9, it is determined whether or not the first sensor 21a is emitting a pulse P1. If it is detected that the first sensor 21a emits the pulse P1, the process proceeds to step S52. If it is not detected that the first sensor 21a emits the pulse P1, the process proceeds to step S54.

  In step S52, it is determined whether or not the second sensor 21b is emitting a pulse P2. If it is detected that the second sensor 21b is emitting a pulse P2, the process returns to the main routine. If it is not detected that the second sensor 21b is emitting a pulse P2, the process proceeds to step S53. In step S53, it is detected that the first sensor 21a emits the pulse P1, and the second sensor 21b does not detect that the pulse P2 is emitted, so that the second sensor 21b breaks down. The motor 12 is turned off and the process returns to the main routine.

  In step S54, it is determined whether or not the second sensor 21b is emitting a pulse P2. If it is detected that the second sensor 21b is emitting a pulse P2, the process proceeds to step S55. If it is not detected that the second sensor 21b is emitting a pulse P2, the process proceeds to step S56. In step S55, it is not detected that the first sensor 21a is emitting the pulse P1, but is started in a state where it is detected that the second sensor 21b is emitting the pulse P2, so that the first sensor 21a fails. The motor 12 is turned off and the process returns to the main routine.

  In step S56, since the first sensor 21a and the second sensor 21b are not detected to detect that the pulses P1 and P2 are emitted, both the first sensor 21a and the second sensor 21b are out of order. There may be two states: a state, or a state in which both the first sensor 21a and the second sensor 21b do not fail and the drag is operated by pulling fish or the like and the spool 10 is not rotating. Therefore, in step S56, warning processing is performed in which a warning is displayed on the display unit 5 so that the angler can grasp the state of the spool 10, or an alarm sound is output from the alarm 7. Here, when the drag is activated and the spool 10 is not rotating, the angler continues fishing, and when the spool 10 is rotating, both the first sensor 21a and the second sensor 21b are out of order. The angler operates the power button PB to turn off the motor 12 and returns to the main routine.

  In step S6, it is determined whether another command has been issued. When another command is issued, the process proceeds from step S6 to step S11, and other processing according to the command is performed.

  In the key input process in step S7 shown in FIGS. 7 and 8, it is first determined in step S21 whether or not the power button PB has been pressed. In step S22, it is determined whether or not the upper switch of the acceleration / deceleration switch SK has been pressed. In step S23, it is determined whether or not the lower switch of the acceleration / deceleration switch SK has been pressed. In step S24, whether the shelf memo button TB is pressed, whether the bottom memo button SB is pressed, whether the bottom memo button SB is input for a long time (for example, 3 seconds or more), the bottom memo button SB and the shelf memo button It is determined whether or not another key input such as a simultaneous operation with TB or a key input of the saddle button IB has been performed.

  When the power button PB is pressed in step S21, the process proceeds to step S30. In step S30, it is determined whether or not the motor 12 is on. If the motor 12 is already on, the process proceeds to step S31 and the motor 12 is stopped. If the motor 12 is off, the process proceeds to step S32 to determine whether or not the power button PB is in a frozen state. If this is not a frozen state, the process proceeds to step S37 and the motor 12 is turned on. When the power button PB is in the frozen state, the process proceeds to step S33, and it is determined whether or not the time t of the timer 8 turned on in step S54 exceeds a predetermined freeze release time ta (for example, 30 seconds). Is done. If the time t has not yet exceeded the freeze release time ta, the process proceeds to step S22 while the motor 12 is kept off. When the time t exceeds the freeze release time ta, the process proceeds to step S34, and it is determined whether or not the temperature T of the FET 25a exceeds the upper limit temperature TM set to 80 degrees. Here, when the temperature T is higher than the upper limit temperature TM, the frozen state of the power button PB is not released because the risk of burning of the motor 12 and the like has not been eliminated. If the temperature T is lower than the upper limit temperature TM, the power button PB is released from the frozen state in step S35, the timer 8 is turned off in step S36, and then the motor 12 is turned on in step S37.

  When the upper switch of the acceleration / deceleration switch SK is pressed in step S22, the process proceeds to step S40. In step S40, the gear position is increased. The gear stage SC at this time is stored in the reading unit 28 and displayed on the speed display unit 5e. In step S41, it is determined whether or not the shift stage SC is in the seventh speed. If it is in the seventh speed, the switching unit 41 is switched in step S42, and the booster circuit 42 boosts the supply voltage of the external power source 40. To be supplied to the PWM drive circuit 25. However, when the power button PB is in a frozen state, even if the upper switch of the acceleration / deceleration switch SK is pressed, the process proceeds to step S23 without proceeding from step S22 to step S40.

  When the lower switch of the acceleration / deceleration switch SK is pressed in step S23, the process proceeds to step S43. In step S43, the gear position is lowered. The gear stage SC at this time is also stored in the reading unit 28 and displayed on the speed display unit 5e. In step S44, it is determined whether or not the gear stage SC is 6th speed. If it is 6th speed, the switching unit 41 is switched in step S45 and the supply voltage of the external power supply 40 is not boosted. To supply.

  If another key is input in step S24, the process proceeds to step S46, and another key input process corresponding to the pressed key is performed. For example, when the shelf memo button TB is pressed, the water depth at this time is stored in the display data storage area 30 as the upper shelf position, and the value obtained by subtracting the water depth at that time from the water depth at the bottom is displayed as the bottom shelf position. 30. When the bottom memo button SB is pressed, the water depth at this time is stored in the display data storage area 30 as the water depth of the bottom. When the bottom memo button SB is pressed for 3 seconds or more, the display mode is switched from the top and from the bottom, and when the rewind button IB is pressed, the operation mode is switched to the replay mode.

  In this electric reel, when the motor 12 is on, the first sensor 21a detects that the pulse P1 is emitted and the second sensor 21b does not detect that the pulse P2 is emitted. When it is detected that the sensor 21a is not emitting the pulse P1 and the second sensor 21b is emitting the pulse P2, that is, when it is determined that the first sensor 21a or the second sensor 21b is out of order. The control for turning off the motor 12 is performed. Here, even if the first sensor 21a or the second sensor 21b fails when the motor 12 is on, the motor 12 is turned off. Can be prevented.

[Other Embodiments]
(A) In the above-described embodiment, the electric reel has seven speeds, but the number of speeds is not limited to this. Further, the shift speed is not limited to a constant speed and may be a constant tension. Further, although the speed change is performed by the acceleration / deceleration switch SK, it may be performed by a lever member that can swing in the front-rear direction, for example. Further, the motor 12 may be turned on and off by a lever member instead of the power button PB.

  (B) In the embodiment described above, in the electronic breaker process of FIG. 9, when it is not detected in step S54 that the second sensor 21b is emitting the pulse P2, the process proceeds to step S56 and the warning process is performed. As shown in FIG. 10, instead of the warning process in step S56, the process may proceed to step S57, which is a process for determining whether or not the drag is operating.

  In step S57 shown in FIG. 10, when it is detected that the drag is operated from the drag sensor 23 (see FIG. 11) that is connected to the control unit 20 and detects whether the drag is operated, the first sensor 21a. And it considers that both the 2nd sensor 21b is not out of order, it returns to the process of a main routine, and when it detects that the drag is not act | operating from the drag sensor 23, it transfers to step S58. In step S58, it is considered that both the first sensor 21a and the second sensor 21b are out of order, and the drive of the motor 12 is turned off and the process returns to the main routine. Here, it is not necessary for the angler to stop driving the motor 12 by automatically stopping the driving of the motor 12 when it is detected that the drag is not operating.

  (C) In the above-described embodiment, the spool sensor 21 includes the first sensor 21a and the second sensor 21b including two reed switches. However, the spool sensor 21 is not limited to the reed switch and can generate a pulse. It may be a Hall element.

  In addition, as shown in FIG. 12, the spool sensor 21 may be configured by a first sensor 21a, a second sensor 21b, and a third sensor 21c each including three reed switches.

  The first sensor 21a, the second sensor 21b, and the third sensor 21c detect one or a plurality of magnets (not shown) that rotate in conjunction with the spool 10 and generate pulses. The first sensor 21a and the second sensor 21b If the pulses emitted from the third sensor 21c are pulse P1, pulse P2, and pulse P3, respectively, it is recognized whether the pulses are emitted in the order of pulse P1, pulse P2, and pulse P3, or in order of pulse P3, pulse P2, and pulse P1. Therefore, the rotation direction of the spool 10 can be detected.

  When the process proceeds from step S9 shown in FIG. 6 to step S10, the electronic breaker process of the motor 12 shown in FIG. 13 is performed. The electronic breaker process shown in FIG. 13 is a process of detecting the state of the spool sensor 21 and turning off the motor 12 according to the state of the spool sensor 21, and is started when the motor 12 is turned on.

  First, in step S61 shown in FIG. 13, it is determined whether or not the first sensor 21a is emitting a pulse P1. If it is detected that the first sensor 21a emits the pulse P1, the process proceeds to step S62. If it is not detected that the first sensor 21a emits the pulse P1, the process proceeds to step S66.

  In step S62, it is determined whether or not the second sensor 21b is emitting a pulse P2. If it is detected that the second sensor 21b is emitting a pulse P2, the process proceeds to step S63. If it is not detected that the second sensor 21b is emitting a pulse P2, the process proceeds to step S65. In step S65, it is detected that the first sensor 21a emits the pulse P1 and the second sensor 21b does not detect that the pulse P2 is emitted, so that the second sensor 21b breaks down. The motor 12 is turned off and the process returns to the main routine.

  In step S63, it is determined whether or not the third sensor 21c is emitting a pulse P3. If it is detected that the third sensor 21c is emitting a pulse P3, the process returns to the main routine. If it is not detected that the third sensor 21c is emitting a pulse P3, the process proceeds to step S64. In step S64, since the first sensor 21a and the second sensor 21b detect that the pulse P1 and the pulse P2 are emitted and the third sensor 21c does not detect that the pulse P3 is emitted, the process starts. It is determined that the third sensor 21c has failed, the motor 12 is turned off, and the process returns to the main routine.

  In step S66, it is determined whether or not the second sensor 21b is emitting a pulse P2. If it is detected that the second sensor 21b is emitting a pulse P2, the process proceeds to step S67. If it is not detected that the second sensor 21b is emitting a pulse P2, the process proceeds to step S68. In step S67, it is not detected that the first sensor 21a is emitting the pulse P1, but is started in a state where it is detected that the second sensor 21b is emitting the pulse P2, so that the first sensor 21a fails. The motor 12 is turned off and the process returns to the main routine.

  In step S68, it is determined whether or not the third sensor 21c is emitting a pulse P3. If it is detected that the third sensor 21c is emitting a pulse P3, the process proceeds to step S69. If it is not detected that the third sensor 21c is emitting a pulse P3, the process proceeds to step S70. In step S69, the first sensor 21a and the second sensor 21b do not detect that the pulses P1 and P2 are emitted, and the third sensor 21c is started in a state where it is detected that the pulse P3 is emitted. Then, it is determined that the first sensor 21a and the second sensor 21b are out of order, the motor 12 is turned off, and the process returns to the main routine.

  In step S70, the first sensor 21a, the second sensor 21b, and the third sensor 21c are started in a state where it is not detected that the pulse P1, the pulse P2, and the pulse P3 are emitted. 21b and the third sensor 21c are all in a state of failure, or the first sensor 21a, the second sensor 21b and the third sensor 21c. There can be two states: the drag is actuated by pulling and the spool 10 is not rotating. Therefore, in step S70, warning processing is performed in which a warning is displayed on the display unit 5 so that the angler can grasp the state of the spool 10, or an alarm sound is output from the alarm 7. Here, when the drag is activated and the spool 10 is not rotating, the angler continues fishing, and when the spool 10 is rotating, all of the first sensor 21a, the second sensor 21b, and the third sensor 21c. The angler operates the power button PB to turn off the motor 12 and returns to the main routine.

  Here, even when the spool sensor 21 includes the first sensor 21a, the second sensor 21b, and the third sensor 21c including three reed switches, the motor 12 is turned on as in the above embodiment. Sometimes, even if the first sensor 21a, the second sensor 21b, or the third sensor 21c breaks down, the motor 12 is turned off, so that it is possible to prevent problems related to the control of the motor 12 that occur when the spool sensor 21 breaks down. .
